Going Batty for the Little Brown Bat

The little brown bat (Myotis lucifugus) is a species of mouse-eared bat that lives throughout North America, from northern Canada to the southern United States. They are most commonly found in deciduous forests, but they also roost in man-made structures or caves; anywhere warm and dark.

M. lucifugus is aptly named, as it’s a relatively small bat. At most, individuals weigh 12.5 g (0.44 oz) and have a wingspan of 27 cm (10.6 in). Females are typically larger than males. The color of their fur can range from tan or red to dark brown, though the fur on their stomachs is lighter than the rest of their body. In addition to their large ears, which gives them a great hearing boost, the little brown bat has exceptional eyesight and is sensitive to ultraviolet light. However, they lack a Jacobson’s organ, which in other animals is used to detect moisture-borne odor particles.

Like other bats, the little brown bat is primarily nocturnal, emerging at dusk and feeding intermittently throughout the night. Individuals emit about 20 calls per second while in flight, and use the corresponding information to avoid obstacles and detect prey. They feed exclusively on insects, including mosquitoes, beetles, and flies, and in a single night an individual may consume over 2/3 of its body weight in food. Because their source of food is generally seasonal, little brown bats are only active in the warmer months of the year. When the temperature drops to 0 °C (32 °F), individuals will enter a state of torpor, in which their heart rate may drop as slow as 8 beats per minute.

Mating takes place in the fall, just before the hibernation season. Males and females gather together in large groups to roost, in a behavior known as swarming. During this period, colonies average around 9,000 individuals; the largest recorded had over 180,000. Both sexes mate with multiple partners, and homosexual pairings are relatively common. This behavior continue throughout the hibernation period, and individuals will pair indiscriminately with active and torpid bats. Once mated, female bats store their sperm for the following spring; they then carry their pregnancies for 50-60 days. Each female gives birth to only one pup, which weighs about 30% of her body weight.

Pups grow rapidly, opening their eyes and ears within a few hours of being born and becoming completely weaned at 26 days old. After this, young transition to feeding solely on insects, though they may receive help from their mothers while learning the best techniques for catching prey. Females are sexually mature at only one year old, and males mature at two years old. Once they reach maturity individuals will leave to form their own roosting groups. In the wild, a little brown bat can live up to 34 years; however, many bats are predated upon by owls during the active season, and by raccoons while hibernating.

Conservation status: The IUCN has rated M. lucifugus as Endangered. Their primary threat is a fungus-caused disease known as white-nose syndrome; this disease is particularly harmful to the little brown bat due to their large congregations during the mating and hibernation period.

Bonsoir à tous~

Aujourd'hui je vous propose de découvrir la fiche de la Sérotine bicolore ! 🦇

C'est une espèce que l'on a rarement l'occasion d'observer et pour laquelle on cherche à améliorer nos connaissances sur sa répartition et ses effectifs ! ❤️

Je vous parlais de l'importance de l'acoustique lors de la présentation de ces petites fiches, la Sérotine bicolore est un bon exemple de son utilisation ! Durant l'automne, les mâles "chantent" afin d'attirer les femelles. Ces chants, inaudibles pour nous mais détectables avec les appareils adéquats, sont très caractéristiques pour la Sérotine bicolore. Les études acoustiques et le radiopistage vont ainsi permettre de déterminer les milieux fréquentés par l'espèce, les effectifs,... et ainsi améliorer les connaissances📃

La petite info bonus : Tous les ans des études à ce sujet sont menées dans le massif des Vosges par la CPEPESC Lorraine. C'est en référence à celles-ci que j'ai voulu représenter ma Sérotine bicolore la gueule grande ouverte, comme si elle était en train de chanter 🎶

J'espère que toutes ces informations vous intéressent ! N'hésitez pas si vous avez des questions ou des idées de sujets qui vous plairaient~

Did you know that every Monday night 🌙 I mail out a special newsletter! 🤯 I include excerpts from my occult research, reflections on magical practice, and musings about the interweaving of art and spirit work (also pictures of bats looking ferocious/gorgeous) This week I wrote about Victorian Spiritualism and a little about magic and tabletop RPGs. 🦇 👻 Read all about it: phoebehildegard.substack.com #bat #vespertilionidae #witchcraft #seance #spiritualism https://www.instagram.com/p/CmagJWQLSDx/?igshid=NGJjMDIxMWI=

[mammalidentifier]

can you pretty please identify these funny walkers for me

thamk you :3

The second one is an easy identification: that’s a common vampire bat (Desmodus rotundus)! They’re the only species of bat capable of fully supporting themselves on their wings and walking like that.

The first one is a little trickier because of the angle the video was taken from. The tail placement puts it in the family Vespertilionidae, and the ear placement is making me think Mouse-eared bat (Myotis). Maybe southern myotis (Myotis macropus) or Peters's myotis (Myotis ater)? Ultimately, I’d have to either see this little guy’s face or have a general idea of where it was spotted to narrow it down further!

Vespertillonid bats?

You might've been reading a Repost of one of my posts. I rarely call a bat by it's scientific name ( common names are more easily understood and I don't have binomial memorized as a concept for bats) But they were likely reffering to Vespertilionidae , a family of Microbats Which may or may not have been the family of bat in the post, as I do not know where you've seen this Word.
